The high-intensity and monochromatic radiation sources in the water window spectral range are desirable for many applications. One of potential candidates soft X-ray is polarization produced by a charged particle passing through thin foil. In near absorption edges target material, real part dielectric permittivity can exceed unity, Tamm–Frank criterion fulfilled. Thus, two types produced: transition Cherenkov radiation. this report, we theoretically investigated characteristics both cases...
In this paper, we have investigated characteristics of ultraviolet and visible radiation generated by the 2.7 MeV electrons. It is shown that Cherenkov (ChR) intensity predominates over scintillations including wavelength shifting cathodoluminescence quenching in pure poly(methylmethacrylate) (PMMA) for such electron energy. To separate ChR scintillations, measured emission spectra orientation dependence PMMA samples compared with GEANT4 model taking into account only mechanism.
In this paper, we want to show how obtain information about the spectrum of runaway electrons with kinetic energy in range T≈ 0.25–2 MeV using Cherenkov radiation (ChR). We use a quartz target as radiator which is tilted so that generated optical photons can leave it. Electrons are light charged particles and such process multiple scattering has significant influence on ChR angular distribution since it blur ChR. spite fact, be obtained by deconvolving distribution.
Fused silica and KBr samples were irradiated with a 2.7 MeV electron beam. The emission of fused in the UV visible regions was studied under various experimental conditions. Numerical simulation optical carried out using GEANT4 computer platform. Simulations energy spectra angular distributions beam electrons performed for different target thicknesses. results reveal effect scattering on distribution Cherenkov radiation thicknesses exceeding path length.
